BMW wiper does not work after pressing the automatic button for the following reasons: Transmission linkage dislocated: It may be that the transmission linkage is not properly connected to the wiper rocker arm. Some arms are fixed to the rocker arm with screws, which may be locked and cannot move. Fuse blown: It may be due to a blown fuse (to prevent circuit overload), which causes the wiper to not work properly. In this case, you need to open the fuse box and check. If a fuse is blown, simply replace it, but remember to turn off all the car's electrical switches before replacement. Motor burned out: During testing, pay attention to whether the motor has abnormal noise, which indicates that the mechanical transmission part of the wiper is rusted or stuck. In this case, immediately turn off the wiper switch to prevent burning out the motor.
My BMW 3 Series also experienced the automatic wiper function not working, which was particularly troublesome when driving in the rain. At that time, I suspected that the windshield near the rain sensor might be dirty, with grime covering the detector and preventing it from sensing the rain. Alternatively, the sensitivity setting might have been too low or the car system had a bug and wasn't responding. I tried cleaning the sensor area on the glass with a soft cloth, which occasionally worked. But to delve deeper, it could be due to a blown fuse, a faulty control module, or an aging motor. BMW models have more sophisticated electronic systems, and not fixing the issue could affect driving safety in the rain. I recommend not attempting DIY repairs and instead taking it to a professional shop for inspection. Remember to clean the sensor during regular maintenance to prevent issues before they arise.
